Description

本発明は、手摺り棒の端部を固定する技術に関するものである。 The present invention relates to a technique for fixing an end portion of a handrail bar.

従来から階段の壁や廊下の壁等の壁面、あるいは手摺り壁の上面に沿って手摺りを取付けることが行われている。手摺りは壁面や手摺り壁の上面に固定する支持ブラケットの先端部の手摺り棒取付け部に手摺り棒を固着具により固着して取付けることで構成してあり、手摺り棒の端部は最端部に位置する支持ブラケットよりも突出しており、この手摺り棒の端部の支持ブラケットよりも突出した部分には保護カバーを被嵌して手摺り棒の端部の保護を行っている。 Conventionally, a handrail is attached along a wall surface such as a staircase wall or a corridor wall, or along an upper surface of a handrail wall. The handrail is constructed by fixing the handrail bar to the handrail bar mounting part at the tip of the support bracket that is fixed to the wall surface or the upper surface of the handrail wall with a fixing tool. It protrudes from the support bracket located at the extreme end, and the end of the handrail bar is covered with a protective cover to protect the end of the handrail bar. .

ところが、このような従来例にあっては、保護カバーを被嵌した手摺り棒の端部が支持ブラケットから先端部が自由端状態となって突出しているため、支持ブラケットから突出した部分に衣服やバッグ等が引っ掛かり易いという問題がある。しかも、従来にあっては、保護カバーを手摺り棒の端部に固定するに当たって、保護カバー取付け専用の固定ねじを使用して取付けており、保護カバー取付け用の固定ねじが必要であり、しかも、固定ねじによる取付け作業が必要で、また、固定ねじが保護カバーの外面に露出するため、ねじ隠しカバーが必要となり、部材の形状が大きくなり、手摺り棒を手で掴んで歩行する際に手摺り棒の端部に大きな形状の保護カバーが存在するため手で掴み難いという問題がある。 However, in such a conventional example, since the end portion of the handrail rod fitted with the protective cover protrudes from the support bracket with the tip end portion being in a free end state, the clothes protruded from the support bracket. There is a problem that bags and bags are easily caught. Moreover, in the past, when fixing the protective cover to the end of the handrail bar, it was installed using a fixing screw dedicated to mounting the protective cover, and a fixing screw for mounting the protective cover was required. When mounting with a fixing screw is required, and the fixing screw is exposed on the outer surface of the protective cover, a screw concealing cover is required, the shape of the member becomes large, and the handrail bar is gripped by hand when walking There is a problem that it is difficult to grasp with a hand because there is a large protective cover at the end of the handrail bar.

そこで、支持ブラケットに保護カバー部を一体に設けた最端部専用の支持ブラケットを形成し、支持ブラケットに一体に設けた保護カバー部に手摺り棒の端部を嵌め込むものが特許文献１等により知られている。このような従来例にあっては、手摺り棒の端部が支持ブラケットから突出せず、衣服やバッグが手摺り棒の突出した端部に引っ掛かったりすることがないようにすることができるが、支持ブラケットとして手摺り棒の端部以外を支持固定するための支持ブラケットとは別に、保護カバー部を一体に設けた最端部専用の支持ブラケットを特別に用意する必要があり、部品点数が多くなるという問題がある。特に、手摺りの支持ブラケットとしては、壁面取付け用の支持ブラケット、あるいは、手摺り壁や腰壁等の上面に取付ける笠木用の支持ブラケット等種類の異なるものがあるが、上記のように、支持ブラケットに保護カバー部を一体に設けた最端部専用の支持ブラケットを形成する場合、最端部専用の支持ブラケットが、壁面取付け用、笠木用というように異なる形態毎にそれぞれ必要となり、この点でも部品点数が増えるという問題がある。
特開平８−３４２４４号公報 Therefore, there is a patent document 1 or the like in which a support bracket dedicated to the outermost end provided integrally with the support bracket is formed on the support bracket, and the end of the handrail bar is fitted into the protective cover provided integrally with the support bracket. Is known by. In such a conventional example, the end portion of the handrail bar does not protrude from the support bracket, and the clothes and the bag can be prevented from being caught by the protruding end portion of the handrail rod. In addition to the support bracket for supporting and fixing other than the end of the handrail bar as a support bracket, it is necessary to prepare a support bracket dedicated to the extreme end with a protective cover part integrated, and the number of parts is There is a problem of increasing. In particular, there are different types of support brackets for handrails, such as support brackets for wall mounting, or support brackets for headboards mounted on the upper surface of handrail walls, waist walls, etc. When forming the support bracket for the endmost part with the protective cover part integrally provided on the bracket, the support bracket for the endmost part is required for each different form such as wall mounting and headboard. However, there is a problem that the number of parts increases.
JP-A-8-34244

本発明は上記の従来の問題点に鑑みて発明したものであって、手摺り棒の端部を保護する保護カバーに衣服やバッグが引っ掛かったりすることがなく、また、保護カバーを手摺り棒に取付けるための保護カバー取付け専用の固定ねじが必要でなく、保護カバーを支持ブラケットと手摺り棒とにがたつき無く容易に固定でき、更に、支持ブラケットとして端部専用のものを必要とせず、また、形態の異なる他の種類の支持ブラケットにも共通の保護カバーを用いて取付けることができる手摺り端部の固定構造を提供することを課題とするものである。 The present invention has been invented in view of the above-described conventional problems, and clothes and bags are not caught on a protective cover that protects an end portion of a handrail bar. There is no need for a dedicated fixing screw for mounting the protective cover, so that the protective cover can be easily fixed to the support bracket and the handrail without rattling, and there is no need for a special end bracket as the support bracket. It is another object of the present invention to provide a handrail end fixing structure that can be attached to other types of support brackets having different forms using a common protective cover.

上記課題を解決するために本発明に係る手摺り端部の固定構造は、手摺り棒１の端部に保護カバー２を被嵌し、該保護カバー２を被嵌した手摺り棒１の端部を保護カバー２を介して支持ブラケット３に固着具９により固着するものにおいて、手摺り棒１の端部に被嵌する一端部が閉塞した筒状の保護カバー２の周部に開口窓部４を設けると共に開口窓部４の周囲を被挟持部５とし、開口窓部４の周囲の被挟持部５の外面を保護カバー２の外周面よりも凹ませて嵌め込み凹部１０を形成すると共に、保護カバー２の周部の被挟持部５の肉厚を他の部位よりも薄肉とし、支持ブラケット３に手摺り棒１の曲率に対応した曲率の手摺り棒取付け部６を設け、該手摺り棒取付け部６に被挟持部５に対応する受け面部７と、開口窓部４に対向する位置に設けた固着具挿入孔８とを設け、受け面部を嵌め込み凹部に嵌め込んだ状態で、固着具挿入孔８から挿入した固着具９が開口窓部４を挿通して保護カバー２が被嵌された手摺り棒１に固着されることで手摺り棒１と受け面部７とにより被挟持部５が挟持されるように構成して成ることを特徴とするものである。 In order to solve the above-mentioned problems, the handrail end fixing structure according to the present invention is such that the end of the handrail rod 1 is fitted with the protective cover 2 on the end portion of the handrail rod 1. In the case where the portion is fixed to the support bracket 3 via the protective cover 2 by the fixing tool 9 , an opening window portion is formed in the peripheral portion of the cylindrical protective cover 2 whose one end portion fitted to the end portion of the handrail rod 1 is closed. 4, the periphery of the opening window 4 is a sandwiched portion 5, the outer surface of the sandwiched portion 5 around the opening window 4 is recessed from the outer peripheral surface of the protective cover 2, and the recess 10 is formed. The thickness of the sandwiched portion 5 on the peripheral portion of the protective cover 2 is made thinner than other portions, and the handrail bar mounting portion 6 having a curvature corresponding to the curvature of the handrail bar 1 is provided on the support bracket 3. At the position facing the receiving surface portion 7 corresponding to the sandwiched portion 5 and the opening window portion 4 on the rod mounting portion 6 The fixing tool 9 inserted through the fixing tool insertion hole 8 is inserted through the opening window 4 and the protective cover 2 is fitted in a state in which the fixing tool insertion hole 8 is provided and the receiving surface portion is fitted in the recessed portion. By being fixed to the handrail rod 1, the sandwiched portion 5 is sandwiched between the handrail rod 1 and the receiving surface portion 7 .

このように手摺り棒１の端部を保護カバー２で保護した状態で、手摺り棒１の端部を保護カバー２を介して支持ブラケット３に固着するので、保護カバー２で保護された手摺り棒１の端部が支持ブラケット３から大きく突出しないものであって、保護カバー２で保護された手摺り棒１の端部に衣服やバッグ等が引っ掛かったりせず安全であり、また、保護カバー２を介して手摺り棒１の端部を支持ブラケット３に固着具９により固着するので、固着具９により支持ブラケット３に手摺り棒１の端部を固着するだけで、同時に保護カバー２を支持ブラケット３と手摺り棒１とに同時にがたつかないように取付けることができ、従来のように保護カバー２を手摺り棒１の端部に固定するための専用の固定ねじが必要でなく、また、手摺り棒１の端部に被嵌する保護カバー２と支持ブラケット３とが別部材であるため、最端部に位置する支持ブラケット３も他の位置で使用する支持ブラケット３と同じものが使用でき、従来のように最端部用の特別な支持ブラケットを必要とせず、また、壁面取付け用、笠木用、出隅用というように異なる形態毎にそれぞれ保護カバー２を兼用できる。 Since the end portion of the handrail rod 1 is secured to the support bracket 3 via the protective cover 2 in a state where the end portion of the handrail rod 1 is protected by the protective cover 2, the hand protected by the protective cover 2 is used. The end of the slide bar 1 does not protrude greatly from the support bracket 3, and it is safe because clothes or bags are not caught on the end of the handrail bar 1 protected by the protective cover 2. Since the end portion of the handrail rod 1 is fixed to the support bracket 3 by the fixing tool 9 via the cover 2, the protective cover 2 can be simultaneously secured only by fixing the end portion of the handrail rod 1 to the support bracket 3 by the fixing device 9. Can be attached to the support bracket 3 and the handrail bar 1 at the same time, and a dedicated fixing screw for fixing the protective cover 2 to the end of the handrail bar 1 as in the prior art is required. And the end of the handrail 1 Since the protective cover 2 and the support bracket 3 fitted to each other are separate members, the support bracket 3 located at the extreme end can be the same as the support bracket 3 used at other positions. There is no need for a special support bracket for the end portion, and the protective cover 2 can be used for each of different forms such as wall mounting, headboard and projecting corner.

また、保護カバー２を手摺り棒１の端部に被嵌した状態で支持ブラケット３の手摺り棒取付け部６に当接した状態で、固着具挿入孔８から挿入した固着具９を手摺り棒１に固着するだけで、支持ブラケット３に手摺り棒１の端部を直接固着することができると共に、固着具９による支持ブラケット３と手摺り棒１との固着により同時に保護カバー２が挟持されて保持固着されることになって、保護カバー２が支持ブラケット３、手摺り棒１の双方にがたつきなく確実に保持固着される。 Further, the fixing tool 9 inserted from the fixing tool insertion hole 8 is handrailed while the protective cover 2 is fitted on the end of the handrail bar 1 and in contact with the handrail bar mounting portion 6 of the support bracket 3. The end of the handrail bar 1 can be directly fixed to the support bracket 3 simply by fixing to the bar 1, and the protective cover 2 is simultaneously held by the fixing of the support bracket 3 and the handrail bar 1 by the fixing tool 9. Thus, the protective cover 2 is securely held and fixed to both the support bracket 3 and the handrail bar 1 without rattling.

また、最端部以外の箇所では支持ブラケット３の手摺り棒取付け部６に直接手摺り棒１の周面の一部を当てて固着具９により取付けるので、最端部において保護カバー２を介して手摺り棒１を支持ブラケット３に固着具９により取付けると、被挟持部５の厚みだけ壁面から手摺り棒１までの寸法が長くなり、このため、手摺り棒１が剛性を有する直棒の場合、手摺り棒１の端部を壁面から離れる方向に少し撓ませないと最端部の支持ブラケット３の壁面に取付けることができず、このため最端部の支持ブラケット３の隣に位置する支持ブラケット３が壁面に対して若干浮き気味になったりするが、上記のように被挟持部５の外面を保護カバー２の外周面よりも凹ませることで被挟持部５の厚みを薄くできて、壁面から剛性を有する直棒状の手摺り棒１までの寸法を最端部の支持ブラケット３による保持固着部分においても略同じにできて、端部を保護カバー２により保護した剛性の直棒状の手摺り棒１を最端部の支持ブラケット３による保持固着部分においても他の支持ブラケット３による手摺り棒取付け部の固着と同じように壁面に取付けることができる。 In addition, since a part of the peripheral surface of the handrail bar 1 is applied directly to the handrail bar mounting part 6 of the support bracket 3 at a place other than the end part and attached by the fixing tool 9, the protective cover 2 is interposed at the end part. When the handrail bar 1 is attached to the support bracket 3 by the fixing tool 9, the dimension from the wall surface to the handrail bar 1 is increased by the thickness of the sandwiched portion 5, and therefore the handrail bar 1 is a straight bar having rigidity. In this case, the end of the handrail rod 1 cannot be attached to the wall surface of the endmost support bracket 3 unless it is bent slightly in the direction away from the wall surface, so that it is located next to the endmost support bracket 3. Although the supporting bracket 3 to be lifted is slightly lifted with respect to the wall surface, the thickness of the sandwiched portion 5 can be reduced by denting the outer surface of the sandwiched portion 5 from the outer peripheral surface of the protective cover 2 as described above. Straight bar-like hand that is rigid from the wall The dimensions up to the rod 1 can be made substantially the same at the holding and fixing portion by the support bracket 3 at the end, and the rigid rod-like handrail rod 1 whose end is protected by the protective cover 2 is supported at the end. The holding and fixing portion by the bracket 3 can be attached to the wall surface in the same manner as the fixing of the handrail bar mounting portion by the other support bracket 3.

本発明は、保護カバーを被嵌した手摺り棒の端部を保護カバーを介して支持ブラケットに固着具により固着するので、保護カバーで保護された手摺り棒の端部が支持ブラケットから突出せず、保護カバーで保護された手摺り棒の端部に衣服やバッグが引っ掛かったりせず安全であり、また、保護カバーを手摺り棒と支持ブラケットに保持固定できて、従来のように保護カバーを手摺り棒に固定ねじで固定しなくてもよくて部品点数が少なくなり、取付け工事を簡略化でき、また、手摺り棒の端部に被嵌する保護カバーと支持ブラケットとが別部材であるため、最端部に位置する支持ブラケットも他の位置で使用する支持ブラケットと同じものが使用でき、最端部用の特別な支持ブラケットを必要とせず、また、壁面取付け用、笠木用というように異なる形態が異なっても共通の保護カバーを使用でき、これらの理由により部品点数が少なくなる。更に、被挟持部の外面を保護カバーの外周面よりも凹ませることで被挟持部の厚みを薄くできて、壁面から剛性を有する直棒状の手摺り棒までの寸法を最端部の支持ブラケットによる保持固着部分においても略同じにできて、端部を保護カバーにより保護した剛性の直棒状の手摺り棒を最端部の支持ブラケットによる保持固着部分においても他の支持ブラケットによる手摺り棒取付け部の固着と同じように壁面に取付けることができる。 In the present invention, since the end of the handrail bar fitted with the protective cover is fixed to the support bracket via the protective cover by the fixing tool, the end of the handrail bar protected by the protective cover protrudes from the support bracket. It is safe because clothes and bags do not get caught on the end of the handrail bar protected by the protective cover, and the protective cover can be held and fixed to the handrail bar and the support bracket. There is no need to fix the bracket to the handrail rod with a fixing screw, the number of parts can be reduced, the installation work can be simplified, and the protective cover and the support bracket fitted on the end of the handrail rod can be separated. Therefore, the support bracket located at the end can be the same as the support bracket used at other positions, and no special support bracket for the end is required. Yo Different forms or different use a common protective cover, the number of parts is reduced by these reasons. Furthermore, the thickness of the sandwiched portion can be reduced by denting the outer surface of the sandwiched portion from the outer peripheral surface of the protective cover, and the dimensions from the wall surface to the rigid straight bar-shaped handrail rod can be used as the end support bracket. It can be made substantially the same in the holding and fixing part by the rigid rod-like handrail bar whose end is protected by the protective cover. It can be attached to the wall in the same way as fixing the part.

以下、本発明を添付図面に示す実施形態に基いて説明する。 Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

手摺り棒１の端部を保護する保護カバー２は図７に示すように、一端部が閉塞された有底筒状をしたもので、カバー主体２ａと、カバー副体２ｂとを組み合わせて構成してある。 As shown in FIG. 7, the protective cover 2 that protects the end portion of the handrail bar 1 has a bottomed cylindrical shape with one end portion closed, and is configured by combining a cover main body 2a and a cover sub-body 2b. It is.

カバー主体２ａはアルミニウムのダイキャストにより形成してあり、断面半円状をした半円状部１１の一端部に円板状をした底片部１２が一体に設けてあり、半円状部１１の周方向の両端部の外面部に係止部１３が設けてある。カバー副体２ｂは合成樹脂製で断面半円状をしている。半円状をしたカバー副体２ｂの周方向の両端部の内面部に被係止部１４が設けてある。上記カバー主体２ａの半円状部１１の周方向の両端部にカバー副体２ｂの周方向の両端部を合致させて係止部１３に被係止部１４を係止することで半円状部１１と半円状をしたカバー副体２ｂとで円筒部を構成すると共にこの円筒部の一端が円板状をした底片部１２により閉塞され、これにより一端部が閉塞された有底筒状の保護カバー２を構成する。 The cover main body 2a is formed by die casting of aluminum, and a disc-shaped bottom piece 12 is integrally provided at one end of a semicircular portion 11 having a semicircular cross section. Locking portions 13 are provided on outer surface portions at both ends in the circumferential direction. The cover sub-body 2b is made of a synthetic resin and has a semicircular cross section. Locked portions 14 are provided on inner surface portions of both ends in the circumferential direction of the semicircular cover sub-body 2b. A semicircular shape is obtained by engaging both ends in the circumferential direction of the cover sub-body 2b with both ends in the circumferential direction of the semicircular portion 11 of the cover main body 2a and locking the locked portion 14 to the locking portion 13. The cylindrical portion is constituted by the portion 11 and the semicircular cover sub-body 2b, and one end of the cylindrical portion is closed by a disk-shaped bottom piece portion 12, and thereby the one end portion is closed. The protective cover 2 is configured.

ここで、保護カバー２をカバー主体２ａと、カバー副体２ｂとの２部材を組み合わせて構成したのは以下の理由による。すなわち、一端部が閉塞された有底筒状の保護カバー２をダイキャストや射出成形により成形しようとすると、有底筒状の保護カバー２の円筒部の内部は型抜きのための抜き勾配を取る必要があり、このため、円筒部の内部の径は開口端部側程大きくなり、このようにして形成したものは手摺り棒１に被嵌した場合、円筒部の開口縁と手摺り棒１の外面との間に小隙間が発生してがたつくという問題があるが、上記のように円筒部を軸方向に２つ割りしたカバー主体２ａと、カバー副体２ｂとの２部材を組み合わせて構成すると、円筒部の内部の径は軸方向の各部で同じとなり、手摺り棒１に被嵌した場合、円筒部の開口縁と手摺り棒１の外面との間に小隙間が発生しない。 Here, the reason why the protective cover 2 is configured by combining two members of the cover main body 2a and the cover sub-body 2b is as follows. That is, when the bottomed cylindrical protective cover 2 whose one end is closed is to be molded by die casting or injection molding, the inside of the cylindrical portion of the bottomed cylindrical protective cover 2 has a draft for die cutting. For this reason, the inside diameter of the cylindrical portion becomes larger toward the opening end portion side, and when the one formed in this way is fitted on the handrail rod 1, the opening edge of the cylindrical portion and the handrail rod There is a problem that a small gap is generated between the outer surface of the cover 1 and the rattle, but as described above, the cover main body 2a obtained by dividing the cylindrical portion into two in the axial direction and the cover sub body 2b are combined. If comprised, the inside diameter of a cylindrical part becomes the same in each part of an axial direction, and when it fits on the handrail bar 1, a small clearance gap does not generate | occur | produce between the opening edge of a cylindrical part, and the outer surface of the handrail bar 1. FIG.

カバー主体２ａの半円状部１１の周方向の中間部には開口窓部４が設けてあり、開口窓部４の周囲が被挟持部５となっている。この開口窓部４の周囲の被挟持部５の外面は保護カバー２の外周面よりも凹ませてあって嵌め込み凹部１０となっており、このように被挟持部５の外面を保護カバー２の外周面よりも凹ませることで被挟持部５の肉厚を保護カバー２の他の部位の肉厚よりも薄肉としてある。 An opening window portion 4 is provided at the circumferential intermediate portion of the semicircular portion 11 of the cover main body 2a, and the periphery of the opening window portion 4 is a sandwiched portion 5. The outer surface of the sandwiched portion 5 around the opening window 4 is recessed from the outer peripheral surface of the protective cover 2 to form a fitting recess 10, and thus the outer surface of the sandwiched portion 5 is used as the protective cover 2. By being recessed from the outer peripheral surface, the thickness of the sandwiched portion 5 is made thinner than the thickness of other portions of the protective cover 2.

支持ブラケット３は、図１乃至図６に示すような手摺り壁の上面に取付けるための笠木用の支持ブラケット３Ａや、図９乃至図１０に示すような階段の壁や廊下等の壁の出隅部に取付ける出隅用の支持ブラケット３Ｂや、図１１乃至図１３に示すような壁用の支持ブラケット３Ｃ等がある。 The support bracket 3 is provided with a support bracket 3A for a cap for attaching to the upper surface of a handrail wall as shown in FIGS. 1 to 6, and a wall of a staircase or a corridor as shown in FIGS.

It is attached by holding and fixing to the handrail bar mounting portion 6 of the bracket 3 or by fixing the plurality of support brackets 3 to the wall 30 with the plurality of support brackets 3 attached to the handrail bar 1. .

なお、笠木用の支持ブラケット３Ａにおけるブラケット本体３ａは図２に示すように、ベース部１６を壁３０（手摺り壁の上面）に取付けた状態で胴部１５が手摺り壁の上面に対して直角に突出するようになっている。また、出隅用の支持ブラケット３Ｂにおけるブラケット本体３ａは、図９に示すようにベース部１６を階段の壁や廊下等の壁３０の出隅部に配置した場合、出隅部に位置決めできるようにベース部１６の背面部が断面Ｌ字状をしていて該断面Ｌ字状をしたベース部１６の背面部を壁３０の出隅部の両面に当てることで、出隅部の正確な位置に確実に取付けることができるように構成してある。また、壁用の支持ブラケット３Ｃにおけるブラケット本体３ａは、図１１乃至図１３に示すように略Ｌ字状をしている。 As shown in FIG. 2, the bracket main body 3a of the support bracket 3A for the caps has the trunk portion 15 with respect to the upper surface of the handrail wall with the base portion 16 attached to the wall 30 (the upper surface of the handrail wall). It protrudes at a right angle. Further, the bracket body 3a in the support bracket 3B for the protruding corner can be positioned at the protruding corner portion when the base portion 16 is disposed at the protruding corner portion of the wall 30 such as the wall of the staircase or the hallway as shown in FIG. The back surface of the base portion 16 has an L-shaped cross section, and the back surface portion of the base portion 16 having the L-shaped cross section is applied to both sides of the protruding corner portion of the wall 30 so that the exact position of the protruding corner portion is It is configured so that it can be securely attached to. Further, the bracket body 3a in the wall support bracket 3C has a substantially L-shape as shown in FIGS.

壁３０への支持ブラケット３の取付けは、図４、図５、あるいは図１０、あるいは図１２、図１３に示すように、ベース部材３ｃに設けた固着具挿通孔２２から固着具２５を挿入して壁３０に固着するものである。つまり、本発明においては、ブラケット本体３ａは直接固着具２５で壁３０に取付けることなく、ブラケット本体３ａにねじ具２３で取付けたベース部材３ｃを固着具２５で壁３０に取付けることでブラケット本体３ａを間接的に取付けるようになっており、これにより、ブラケット本体３ａが破損した場合などねじ具２３を外すことで壁３０にベース部材３ｃを残したままブラケット本体３ａを取外すことができ、交換して取付ける場合はねじ具２３を用いてベース部材３ｃに取付けることで、固着具２５を取外す必要がない。 As shown in FIG. 4, FIG. 5, FIG. 10, FIG. 10, FIG. 12, or FIG. 13, the fixing bracket 25 is inserted into the wall 30 through the fixing tool insertion hole 22 provided in the base member 3c. It is fixed to the wall 30. That is, in the present invention, the bracket body 3a is not directly attached to the wall 30 with the fixing tool 25, but the base member 3c attached to the bracket body 3a with the screw tool 23 is attached to the wall 30 with the fixing tool 25. Thus, the bracket body 3a can be removed with the base member 3c remaining on the wall 30 by removing the screw 23, such as when the bracket body 3a is damaged. When attaching to the base member 3c using the screw tool 23, there is no need to remove the fixing tool 25.

手摺り棒１は外面に長手方向にわたって位置決め用凹部２６が設けてあり、この手摺り棒１の端部に前述の図７に示すような保護カバー２を被嵌する。保護カバー２を手摺り棒１の端部に被嵌した状態で手摺り棒１の手摺り棒取付け部６に近づけ、手摺り棒取付け部６に突設した位置決め用突部２４を開口窓部４内に挿入して位置決め用凹部２６に嵌め込むと共に、この状態で手摺り棒１に対して保護カバー２を周方向に少し回して嵌め込み凹部１０に手摺り棒取付け部６の受け面部７を嵌め込んで被挟持部５に受け面部７を当接する。 The handrail rod 1 is provided with a positioning recess 26 on the outer surface in the longitudinal direction, and the protective cover 2 as shown in FIG. 7 is fitted to the end portion of the handrail rod 1. With the protective cover 2 fitted to the end of the handrail rod 1, the positioning projection 24 projecting from the handrail rod mounting portion 6 is brought close to the handrail rod mounting portion 6 of the handrail rod 1 and the opening window portion. 4 is inserted into the positioning recess 26 and, in this state, the protective cover 2 is slightly turned in the circumferential direction with respect to the handrail rod 1 to insert the receiving surface portion 7 of the handrail rod mounting portion 6 into the recess 10. The receiving surface portion 7 is brought into contact with the sandwiched portion 5 by being fitted.

このように手摺り棒１と支持ブラケット３の手摺り棒取付け部６との位置決め及び手摺り棒１の端部に嵌め込んだ保護カバー２と支持ブラケット３との位置決めを行った状態で、複数の固着具挿入孔８からそれぞれ固着具９を挿入して手摺り棒１に固着することで、手摺り棒１の周方向の所定位置に手摺り棒取付け部６を取付けることができる。上記のように固着具９を固着すると、保護カバー２の開口窓部４の周囲の被挟持部５が手摺り棒１と受け面部７とにより挟持され、保護カバー２が手摺り棒１と支持ブラケット３とに保持固定されることになる。なお、手摺り棒１の端部に被嵌する保護カバー２は笠木用の支持ブラケット３Ａ、出隅用の支持ブラケット３Ｂ、壁面用の支持ブラケット３Ｃのいずれに取付ける場合も同じ（形状及び大きさが同じ）保護カバー２を共用して使用するようになっており、これにより部品の種類を少なくできる。 In this state, the positioning of the handrail bar 1 and the handrail bar mounting portion 6 of the support bracket 3 and the positioning of the protective cover 2 fitted to the end of the handrail bar 1 and the support bracket 3 are performed. By inserting the fixing tool 9 from each of the fixing tool insertion holes 8 and fixing the fixing tool 9 to the handrail bar 1, the handrail bar mounting portion 6 can be attached to a predetermined position in the circumferential direction of the handrail bar 1. When the fixing tool 9 is fixed as described above, the sandwiched portion 5 around the opening window portion 4 of the protective cover 2 is sandwiched between the handrail rod 1 and the receiving surface portion 7, and the protective cover 2 is supported by the handrail rod 1. It is held and fixed to the bracket 3. The protective cover 2 fitted to the end of the handrail rod 1 is the same when mounted on any one of the support bracket 3A for the headboard, the support bracket 3B for the protruding corner, and the support bracket 3C for the wall surface (shape and size). Is the same), and the protective cover 2 is used in common, thereby reducing the number of parts.

ここで、補強部材３ｄの取付け部分においては補強部材３ｄの他端部に設けた孔２９から固着具９を挿入して固着具挿入孔８を通して手摺り棒１に固着するものであり、これにより、手摺り棒１はブラケット本体３ａと、補強部材３ｄとに固着具９で固着されることになり、また、補強部材３ｄは既に述べたようにねじ具２３によりベース部材３ｃに固着し、ベース部材３ｃを壁３０に固着してあるので、アルミダイキャスト製のブラケット本体３ａが仮に外力により破損してもステンレス製の補強部材３ｄ、ベース部材３ｃを介して手摺り棒１が壁３０に固定してあることで、壁３０から手摺り棒１が外れないようにできる。 Here, at the attachment portion of the reinforcing member 3d, the fixing tool 9 is inserted from the hole 29 provided at the other end of the reinforcing member 3d and fixed to the handrail rod 1 through the fixing tool insertion hole 8, thereby The handrail bar 1 is fixed to the bracket body 3a and the reinforcing member 3d by the fixing tool 9, and the reinforcing member 3d is fixed to the base member 3c by the screw tool 23 as described above. Since the member 3c is fixed to the wall 30, even if the aluminum die-cast bracket body 3a is damaged by an external force, the handrail rod 1 is fixed to the wall 30 via the stainless steel reinforcing member 3d and the base member 3c. Thus, the handrail bar 1 can be prevented from being detached from the wall 30.

ブラケット本体３ａの凹所２７の開口部にブラケットカバー３ｂを着脱自在に取付けて凹所２７を覆い隠す。 A bracket cover 3b is detachably attached to the opening of the recess 27 of the bracket body 3a to cover the recess 27.

一方、手摺り棒１の端部以外の部位では手摺り棒１の周部の一部に支持ブラケット３の手摺り棒取付け部６を直接当てて位置決め用突部２４を位置決め用凹部２６に嵌め込んで手摺り棒１と支持ブラケット３との位置決めをした状態で複数の固着具挿入孔８からそれぞれ固着具９を挿入して手摺り棒１と支持ブラケット３とを固着する。該手摺り棒１の端部以外の部分と固着する支持ブラケット３の壁３０への取付けは前述の通りである。 On the other hand, in a portion other than the end portion of the handrail rod 1, the handrail rod mounting portion 6 of the support bracket 3 is directly applied to a part of the peripheral portion of the handrail rod 1 and the positioning protrusion 24 is fitted into the positioning recess 26. In the state where the handrail bar 1 and the support bracket 3 are positioned, the handrail bar 1 and the support bracket 3 are fixed by inserting the fixing tools 9 from the plurality of fixing tool insertion holes 8 respectively. The mounting of the support bracket 3 to be fixed to the portion other than the end portion of the handrail rod 1 to the wall 30 is as described above.

ここで、支持ブラケット３として笠木用の支持ブラケット３Ａを用いて手摺り棒１を手摺り壁の上面に取付ける場合、手摺り棒１の端部及び端部以外の部位のいずれにおいても同じ笠木用の支持ブラケット３Ａを用いて取付けるものである。 Here, when the handrail bar 1 is attached to the upper surface of the handrail wall using the support bracket 3A for the headboard as the support bracket 3, the same headboard is used for both the end portion of the handrail rod 1 and portions other than the end portion. The support bracket 3A is used for attachment.

また、支持ブラケット３として壁面用の支持ブラケット３Ｃを用いて手摺り棒１を手摺り壁の上面に取付ける場合、手摺り棒１の端部及び端部以外の部位のいずれにおいても同じ壁面用の支持ブラケット３Ｃを用いて取付けるものである。 Further, when the handrail bar 1 is attached to the upper surface of the handrail wall by using the wall support bracket 3C as the support bracket 3, the end of the handrail bar 1 and the portion other than the end portion are used for the same wall surface. It is attached using the support bracket 3C.

なお、支持ブラケット３が出隅用の支持ブラケット３Ｂの場合、手摺り棒１を壁３０の出隅部に縦に取付けるので、手摺り棒１の上下両端部に保護カバー２を被嵌した状態で保護カバー２を介して手摺り棒１の上下両端部をそれぞれ出隅用の支持ブラケット３Ｂに固定し、手摺り棒１の端部以外の部位では出隅用の支持ブラケット３Ｂを取付けないが、手摺り棒１が上下に長くて端部以外の部位に出隅用の支持ブラケット３Ｂを取付ける場合は、同じ出隅用の支持ブラケット３Ｂを使用する。 When the support bracket 3 is the support bracket 3B for the protruding corner, the handrail rod 1 is vertically mounted on the protruding corner portion of the wall 30, so that the protective cover 2 is fitted on both the upper and lower ends of the handrail rod 1. Thus, the upper and lower ends of the handrail bar 1 are fixed to the support bracket 3B for the protruding corner respectively through the protective cover 2, and the support bracket 3B for the output corner is not attached at a portion other than the end of the handrail bar 1. When the handrail bar 1 is long in the vertical direction and the support bracket 3B for the protruding corner is attached to a portion other than the end portion, the same support bracket 3B for the protruding corner is used.

これにより端部専用の笠木用の支持ブラケット３Ａ、端部専用の出隅用の支持ブラケット３Ｂ、端部専用の壁面用の支持ブラケット３Ｃが必要でない。 This eliminates the need for the support bracket 3 </ b> A dedicated to the end, the support bracket 3 </ b> B dedicated to the end corner, and the wall support bracket 3 </ b> C dedicated to the end.

ところで、本発明において、手摺り棒１の端部においては、上記のように、保護カバー２の周壁部の一部である被挟持部５が手摺り棒１と支持ブラケット３との間に介在されて取付けられるので、この保護カバー２を被嵌した手摺り棒１の端部を支持ブラケット３に取付けると、最端部以外の箇所で支持ブラケット３の手摺り棒取付け部６に直接手摺り棒１の周面の一部を当てて固着具９で固着する場合に比べ、被挟持部５の肉厚分だけ壁面のような壁３０から手摺り棒１までの寸法が長くなるが、本発明においては、被挟持部５の外面を保護カバー２の外周面よりも凹ませて被挟持部５の厚みを薄くしているので、壁３０から手摺り棒１までの寸法を最端部の支持ブラケット３による保持固着部分においても略同じにできて、端部を保護カバー２により保護した剛性の直棒状の手摺り棒１を最端部の支持ブラケット３による保持固着部分においても他の支持ブラケット３による手摺り棒取付け部固着と同じように壁面に取付けることができる。 By the way, in the present invention, at the end portion of the handrail rod 1, the sandwiched portion 5, which is a part of the peripheral wall portion of the protective cover 2, is interposed between the handrail rod 1 and the support bracket 3 as described above. Therefore, when the end portion of the handrail rod 1 fitted with the protective cover 2 is attached to the support bracket 3, the handrail is directly applied to the handrail rod attachment portion 6 of the support bracket 3 at a place other than the end portion. Compared with the case where a part of the peripheral surface of the bar 1 is applied and fixed by the fixing tool 9, the dimension from the wall 30 like the wall surface to the handrail bar 1 is increased by the thickness of the sandwiched portion 5. In the invention, since the outer surface of the sandwiched portion 5 is recessed from the outer peripheral surface of the protective cover 2 to reduce the thickness of the sandwiched portion 5, the dimension from the wall 30 to the handrail bar 1 is set to the endmost portion. The holding and fixing portion by the support bracket 3 can be made substantially the same, and the end portion is protected. The rigid straight bar-shaped handrail bar 1 protected by -2 can be attached to the wall surface in the same manner as the handrail bar mounting portion fixed by the other support bracket 3 even at the holding fixing portion by the support bracket 3 at the end. .

なお、本発明において、保護カバーに開口窓部４を設けた例を示したが、開口窓部に代えて固着具挿入孔８と対向する位置に固着具９を挿通するための孔を設けてもよい。 In the present invention, an example in which the opening window portion 4 is provided in the protective cover has been shown. However, a hole for inserting the fixing tool 9 is provided at a position facing the fixing tool insertion hole 8 instead of the opening window portion. Also good.
